telemedicine and ventilator titration in chronic respiratory patients initiating non-invasive ventilation

Conditions: Chronic Obstructive Pulmonary Disease; Neuromuscular Disease; Chest Wall Disorders; Obesity Hypoventilation Syndrome

Summary: the critical nature of respiratory diseases, the continuously increasing prevalence of these conditions, and the subjective perception of patients vis-à-vis their pulmonary function and health status underscore the importance of home telemonitoring. these conditions are critical and necessitate close and regular monitoring that may be achieved at distance using telemonitoring. this study will assess a number of measures both at baseline and post-intervention from a number of domains, including arterial blood gases (abg), bipap-related data, chronic respiratory failure symptoms, health-related quality of life, patients satisfaction and utilization of healthcare resources.

in recent years home care is becoming increasingly used and considered by some the future of healthcare. home mechanical ventilation has been shown to improve morbidity and mortality in patients with chronic respiratory failure of different aetiologies. a french survey suggests an increase of 12% of cases per year. with the prospect of a substantial increase of ventilated patients at home, facilities and resources have not been proportionally growing, so new approaches should be investigated and addressed to absorb this constant flux of patients. telemedicine is defined as the broad use of electronic and communications technologies to provide and support remote monitoring of health status. it has been shown to be an effective alternative model of care for managing chronic diseases. it as also been shown to reduce healthcare costs and is a major topic on the agendas of health and social care policies in europe. home telemonitoring of respiratory conditions results in early identification of deteriorations in patient condition and symptom control. however, evidence on the magnitude of clinical and structural effects remains preliminary, with variations in study approaches and an absence of robust study designs and formal evaluations. the objective is gathering data that can be help to establish guidelines for non invasive home mechanical ventilation initiation and quality control.
